I v

button has two eyes, andthe buttons'areaiy ranged in rows transversely ofthe 'cardwithfli. l

the eyes of theseveralbuttons in lin'es ex} tending longitudinally off-the carde Each 'buttonis secured on the face of the card by a looped portion of Mhread, 4, vh'aSsed" from the back or'opposite side of thfe card through the card'at', 5', an'dithrough a 'but q through "the other inserted through the loop. 'Thethread, 1,

ppo Si f. h' e 5 ei? s he e d of the loop exposed at theback'ofthe card' whereit is secured by a locking thread, 9,

has thus'a' loop, 8', for eachbutton iir'feach row extending transversely of the card, I

' tons respectively in said next successive row,

looped portions of said thread being passed from the back of the card each through one eye of a button in said next successive row, back through the other eye ofsaid button, and through the card to the back thereof, where all the loops of the latter row are secured by a continuation of the thread 9. The thread, 9, extends in one direction transversely of the card through the loops, 3,

I whereby one row of buttons is secured; then longitudinally of the card to the next successive row of buttons, and then in the opposite direction transversely of the card through the loops, 3, in said next successive row of buttons, and so on indefinitely; while the thread, 4, extends from the outermost buttons in a preceding row to the middle two buttons respectively in each successive row indefinitely. By this method of attaching the buttons to the card, the only threads exposed to view on the face of the card are the loops passing from eye to eye of each button, there being exposed on the face of the card no thread extending from button to button.

An important feature of my invention consists in sewing mechanism whereby buttons can be attached in the manner above described to produce a card of buttons as shown. Referring to the drawings, where in said sewing mechanism or machine is shown in preferred form, 12, is the bedplate of the machine mounted upon a base, 13, said base having also mounted thereon the overhanging arm, 14, terminating in the head, 15, upon which head is pivotally mounted, upon a vertical axis at, 16, the oscillatory yoke, 17, containing slide bearings for the needle-bar, 18, adapted to be re vciprocated at certain times longitudinally "in the slide-bearings in said yoke by means of a link-connection, 19, with one arm of a lever, 20, fulcrumed at, 21, upon the overhanging arm, 14,.and connected by means of a pitman, 22, with an eccentric, 23, fixed upon the main shaft, 24, of the machine, to which shaft rotary movements can be im parted by means of the crank-handle, 25, or in any other known manner.

Oscillating movements are imparted to the yoke, 17, at certain times by means of a rocker-arm, 26, fixed upon a rock-shaft, 27,

and ivotally connected at, 28, with an arm, 29, 'xed upon said yoke, 17, whereby said yoke, 17, is caused to oscillate in accordance with the rocking movements of the shaft, 27. The rock-shaft, 27, has also fixed thereon a rocker-arm, 30, connected by a link, 31, with a lever, 32, fulcrumed at, 33, upon the post of the overhanging arm, 14, said lever, 32, having on its lower end a yoke, 34, adapted to receive the cam-wheel, 35, fixed upon the gear, 36, rotatively mounted upon a stud fixed upon the post of the overhanging arm. The gear, 36, meshes with, and is driven by, a pinion, 37, fixed on the main shaft 24.

Fixed upon the lower end of the needlebar, 18, is a head, 38, upon which are rotatively mounted a plurality of needle-posts, 39, each carrying a needle 40. Fixed upon each of said needle-posts, 39, is a rockerarm, 41, all of said rocker-arms, 41, being pivotally connected with a common link, 42, by longitudinal reciprocation of which the needle-posts are adapted to be rocked on their respective axes through an arc of substantially 90 degrees, as indicated by dotted lines in Fig. 7

Reciprocating movements are imparted to the link, 42, at certain times by means of a post, 43, which projects upward from a slide, 44, movable along a slideway in the base of the machine, and having a depending arm, 46, carrying a cam-follower, 47, adapted to occupy a cam-groove, 48, in the cam-wheel, 49, fixed upon a cam-shaft, 50, rotatively'mounted in bearings on the base of the machine beneath the bed-plate, and adapted to be driven from the main driveshaft, 24, through the intermeshing pinion, 51, on said main shaft, and the gear, 52, on said camshaft, 50, as shown in Fig. 4.

The end of the link, 42, through which the post, 43, passes is offset, as shown at 54, and. provided with an elongated slot, 55, to provide for the transverse movement of the link, 42, induced by-the oscillating movement of the yoke, 17, and this slotted end of said link, 42, is adapted to slide freely up and down upon the post, 43, as said link accompanies the needle-bar, 18, in its vertical, reciprocating movements.

Beneath the bed-plate, adjacent to the path of vertical, reciprocating movement of the needles in one position of the yoke, 17,

is a shuttleraceway, 56, open on the side toward said needles, and adapted to receive and form 'a slideway for a shuttle-carrier, 57, which shuttle-carrier is formed with a recess, 58, open at its opposite ends and on the side toward the needles, and adapted to receive a double-pointed shuttle, 59, which isloosely confined within said recess, and is of a size adapted to permit the free passage of loops of thread delivered by the respec 'tive needles between said shuttle and the 1,145,353 Y a i Walls of said recess. The shuttle-carrier, 57, has depending therefrom a cam-follower, 60, adapted to occupy a spiral cam-groove, 61, in the cam-roller, 62, upon the shaft of which is fixed a pinion, 63, in mesh with a sliding gear-rack, 64:, reciprocatory in aslideway, 53, in the base of the machine.

Reciprocating movements are imparted to the rack, 64:, by means of a lever, 65, fulcrumed at, 66, one end of which lever has a pin-and-slot connection at, 67, with said gear-rack, 64, and the other end of which lever has a cam-follower, 68, adapted to occupy the double-grooved cam-raceway, 69, on the. periphery of the cam-wheel 49. The lever, 65, is offset from the plane of the gear-rack, 64, to the plane of the top of the cam-wheel, 49, as shown in Figs. 1, 2 and 9.

The bed-plate of the machine is apertured, as shown at, 70, to permit the several needles to pass down therethrough adjacentto the open side of the shuttle-raceway, and is also apertured at, 71', to permit the needles to pass down therethrough at a distance from the aperture, 70, equal to the distance between the two eyes of a button of the] style for which the machine is adapted.

The aperture, 71', is in the form of a continuous slot which isal'so adapted to form a guideway for a pair of thread-guides, 72, movable toward and from each other in said slot. Said thread-guides,-72, are adapted to be so moved from the position shown by solid lines in. Fig. 5, in which position they are outside of the'outermost needles, to the position indicated bydotted lines in said figure, in which positionsaid guides occupy positions contiguous to each other, and between the middle two needles. Adjacent to the outermost positions occupied by the movable thread-guides, 72, are stationary thread-guides, 73, for the thread from two spools, 74, supported upon the respective posts or spindles and frictionally held thereon by the thumb-nuts 76.

The movable thread-guides, 72, are fixed each to a slide, 78, movable in a slideway, 82, in the base of the machine, each having a depending'arm, 79, on the end of which is a cam-follower adapted to occupy one of the two spiral grooves, 80,- in the cam-roll,

81, beneath the bed of the machine, one of said spiral groovesbeing provided for each of said movable thread-guides. Fixed upon the shaft of the cam-roll, 81, is a pinion, 88,

adapted to mesh with a gear-rack, 84:, movable along a slideway, 85, in the base of the machine.

Reciprocatingmovements are imparted to the rack, 84, by means of a lever, 86, fulcrumed at, 87, one end of which lever has a pin-and-slot connection at, 88, with said gear-rack, 84, and the other end of which lever has a cam-follower, 89, adapted to occupy the double-grooved cam-raceway, 90,

on the periphery of the cam-wheel, .91, fixed upon. the main shaft, 24, 'of the machine.

The-lever, 86, is ofl'set'from the planeof the gear-rack, 84, to the plane of thetop of the cam-wheel, 91, as shown in Figs. 3-and 9.

'Movably mounted upon the uppersurface of the bed-[plate of the 'machine'is a work-f holder comprising 'a plate, i92, havingv a clamp, 93, mounted thereon, and adapted to} t be forced toward the plate' by means of a cam 94. The card'to which thebuttons are to-be attached by'my improvedpmachine is clamped at one end between said 'plane'and' clamp; The plate, 92, is provided with a longitudinal slot, 95, adapted to receivea stationary guide, 96, whereby the plate, 92, is guided in its movementsalong the bedplate of the machine. On one edge of the plate, 92, is a gear-rack, 97, adapted to mesh with a pinion, 98, having fixed thereto a crank-handle, 99,-whereby the pinion, which-,

is rotatively' mounted upon the bed, can be' rotated in opposite directions to impart reciprocating movements to the plate 92. V

The buttons for, each row to be attached to the card are supported upon the face of the card by means of the individual chucks,

1.00, mounted upon the chuck-head or but ton-holder, 101, fixed upon the "lower end of the chuck-post, 102,, which postjiscapable of a reciprocating vertical movement in yaf bearing in the head, 15, of theoverhan-gin'g' I arm. A spring, 103, 'tendsto. force the chuck-post downward to carry the chuck? supported buttons against the upper surfaceof the card on the bed, and said post isadapted to be supported in raised position by a cam, 104, while thebuttons arebeing inserted in the chucks. The chucks are adapted to yieldinglyhold the respective buttons inserted therein, and to permitthe buttons when attached to thecard to be forced through the chucks to accompany thecardwhen the card is moved along the bed. Each needle is providedjnear its point serted .in the card-holder and the buttons for a single row areinserted by hand or in any known manner in the respective chucks, and the chucks lowered-upon the card, each button belng arranged wlth its two eyes in a line extending longitudinally of the card. 1

The ends of the threads from the two spools, 74, 7 5, are tied together so that said threads together extend beneath the card across the whole line of needles on the side thereof'toward which the lateral openings, 107, in

the needles face, the thread-guides,72, being 110 v with oppositely facing hooks, 105 and 106, a separated by a lateral opening, 107, out of contiguous to each other in the position in dicated by dotted lines in Fig. 5. A. reciprocating vertical movement is imparted to the needles through the needle-bar, causing the needles to descend, each through one eye, 6, of one of the row of buttons, and through the card, at 5, to the position shown in Fig. 12, and then to return to the elevated position shown in Fig. 13. As the needles return to the elevated position shown in Fig. 13, the thread enters the lower hook of each needle through the opening, 107, and a loop, 3, of said thread is thereby drawn upward through the card at 5, and one eye, 6, of the button 2. For the initial operation it may be found necessary or desirable to draw the thread against the needles to cause it to enter the several needle hooks. This may be done by hand or by passing the thread over the juxtaposed thread-guides 72. After the needles have completed this first reciprocating movement, the thread-guides, 72, are automatically moved apart in the manner above described to the respective positions shown by solid lines in Fig. 5. When the needles are returned to the raised position shown in Fig. 13, the yoke, .17, is swung laterally to bring the respective needles in line with the other eyes, 7, of the respective buttons, and with the needle-aperture, 70, in the bed, in which position a vertical reciprocating movement isimparted to the needles causing them to descend through the respective other eyes, 7, of the buttons and through the card to the position shown in Fig. 14. The swinging movement of the yoke, 17, and consequent movements of the needles cause the needles to pull upon the several loops carried by the respective needles, so that as each needle begins to descend in its new position its loop of thread is drawn intothe upper hook, 105, and carried thereby down through the other eye, 7, of the button and the card to a point somewhat below the plane oi the shuttle-raceway, as shown in Fig. 14. The return movement of the needle from this lowermost position leaves the thread slack, and as the slack loop is forced upward by the lower hook of the needle said loop is forced out into the neighboring shuttle-raceway, and, by the time the hooked part of the needle has reached a point opposite said raceway, said loop will be of sufficient size to receive the shuttle and permit the same to be forced therethrough, such position being shown in Fig. 15. As the needles reach the position last referred to, they are automatically rocked upon their respective axes in the manner above described, causing the openings, 107, to face in a direction at right angles to that in which they face *to receive the thread, which rocking movement of the needles tends to free and release the thread from the hooks thereof, such release being fully accomplished by the pull exerted upon the thread by the frictional contact of the shuttle as the same passes through the several loops 3. The double cam-groove, 69, causes a practically instantaneous movement of the lever, 65, and the shuttle-actuating cam-roll, 62, which movement is timed to occur when the parts are in substantially the position shown in Fig. 15. The shuttlethread, 9, is thus carried through all of said loops, leaving the shuttle at the opposite end of said raceway from which it started, where it remains until a new set of loops is presented in its path. From the position shown in Fig. 15, the needles return to their original initial position preliminary to a repetition of the above described operation. At the conclusion of the operation thus far described, the threads from the respective spools, 74, extend beneath the card to the loops of the respective end buttons of the last attached row on the card. The card is then moved along the bed by means of the crank-operated pinion, 98, and gear-rack, 97, a distance equal to the distance between two successive rows of buttons, thereby withdrawing the attached row of buttons from the chucks. The chucks are then raised, again supplied with buttons, and lowered upon the card preparatory to a repetition of the above described operation. This movement of the card will cause the respective threads from the spools, 74, to be drawn directly from the respective guides, 73, in lines substantially longitudinal of the card, but before the needles again descend to begin the next cycle of movements the movable thread-guides, 72, are brought together to the position indicated by dotted lines in Fig. 5, carrying the threads to the center of the machine, whereby the threads are drawn across the respective needles, and whereby the inclined stretches of thread, 4, are formed. The operation can thus be repeated indefinitely, and with successive 110 cards, it being necessary to tie together the ends of the two threads from the respective spools, 74, only when it is desired to separate the cards of buttons from each other.

The shuttle moves in one direction through 115 the loops whereby one row of buttons is attached to the card, and in the opposite direction through the loops by which the next successive row of buttons is attached to the card. The feed-'movement of the card thus 120 forms short stretches, 9*, of the shuttlethread extending longitudinally of the card from one row of buttons to the next, first along one side of the card, and then along the other, as shown in Fig. 20.

As, after each operation of the needles the card is shifted to bring the next buttonrow opposite the needles, such shifting movement will cause a pull of the thread, 4, upon the loops last formed, as well as upon 130 the spools, 74. This, together with theinward movement of the thread-guides, 72, tends to take up'the slack in {the loops of the thread 4:. The resistance offered *by] the spools, 74-, to such pull upon the thread, 4E,

can be regulated by I eans offlthe thumbnuts 76. i a
